SPICE simulation is a breakthrough innovation for IC industry in the 70's. This technology enables engineers to simulate circuit behavior on the computer. It accelerates the progress on semiconductor IC chip development for the next several decades. Nowadays people call this technology TRUE SPICE.As IC chips become larger and more complex. The TRUE SPICE algorithm starts to become incapable. It take very long time (e.g. over 24 hours) for large digital circuit simulation.
In the 90s', there was another breakthrough for circuit simulation. This is the so-call FAST SPICE. Basically it sacrifices some simulation accuracy but enables 10X more run time improvement. This again accelerates the progress on large digital circuits development.
In 2005, there is another breakthrough. There is no proper name for this technology yet. But the company who own this technology is called Xoomsys. It utilizes parallel grid computing, combined with FAST SPICE and TRUE SPICE. The outcome, 10X run time improvement with 100% TRUE SPICE accuracy.
How the Xoomsys technology can help the IC design industry!? It is yet to determine. But for innovation point of view, this technology solves a years long problem and I vote it as a breakthrough on circuit simulation.
